Abstract
The utility model relates to a calibration method for the oven which is used for measuring water in the tobacco and a method for measuring the water in the tobacco; wherein the calibration method for the oven which is used for measuring water in the tobacco is as follows: a standard sample with known water content is put into the oven to be calibrated to do the test on a prescriptive environmental condition, then the difference between the determination result and the standard value is calculated, then the fan velocity and the heating curve of the oven are adjusted until the determination result and the standard value are uniform according to the difference. The utility model can guarantee the product quality stability and consistency of the same brand tobacco produced by different production lines and different manufacturing sites by calibrating any oven as the tool for calibrating the on-line water determinative instrument.
Description
Technical field
The present invention relates to the method for calibrating drying box for determining tobacco moisture.Further, the invention still further relates to the assay method of moisture in the tobacco.
Background technology
In the tobacco product water content detection, usually with the highest measurement instrument of Oven Method as online Moisture Meter in the calibration process control, the final moisture that detects tobacco product with Oven Method is as unique foundation of judging that moisture is whether qualified.But; because a factory can not have only a baking oven; particularly under new form; merging and reorganization between the tobacco business; the strange land processing of famous brand has become undisputable fact; this has just brought different productions; different baking ovens; there is different difference in the different operating personnel to same test result of samples; this species diversity will be directly delivered to the On-line Control infrared moisture meter; reflection is relatively outstanding is after the pipe tobacco of a processing stand production is delivered to another processing stand and carried out wraparound; baking oven with the locality carries out the finished product water content detection; the phenomenon that occurs Moisture high UCL through regular meeting; in order to solve such contradiction; reach the homogeneity of strange land converted products, press for the method for setting up difference between the different baking oven determinations of moisture of a kind of verification.
Existing method is with through demarcating good thermometer the setting value of oven temperature being carried out verification, if the temperature difference of the two in error range, just thinks that baking oven is accurately.The shortcoming of this method has been to ignore the speed difference of different baking ovens owing to structure and baking oven blower fan, and the difference of heating-up time, the water content detection of same sample in the different baking ovens situation of inconsistency as a result occurs.
Summary of the invention
Purpose of the present invention is exactly the method that will provide a kind of verification to measure the baking oven of tobacco moisture, and then provides a kind of than prior art tobacco moisture assay method accurately.
The method that the baking oven of tobacco moisture is measured in verification provided by the invention is, transfer in the baking oven that needs verification in the environment provided condition with the standard sample of known moisture levels and to measure, calculate the difference between measurement result and the standard value, adjust the fan speed, heating curve of baking oven etc. according to the difference value situation, until detected value with till standard value is consistent.
The standard sample that obtains known moisture levels has diverse ways.Adopt among the embodiment 1 disclosed method to come the preparation standard sample among the present invention.
The preparation of standard moisture sample: after the sample pipe tobacco is pulverized by comminutor, with this batch sample in climatic chamber after the balance, get multiple sample with inquartation and measure its moisture by the standard method of existing determination of moisture in the process baking oven of thermometer calibration, average is as the moisture of its standard moisture sample; With remaining this standard moisture sample break into portions sample, and be contained in, store at temperature and humidity condition lower seal same as described above by in the special-purpose pop can after the balance in identical climatic chamber.
Standard sample so that this kind method obtains though may there be a certain distance in its moisture that records with true moisture, is used as other baking ovens of standard calibration with it, still can overcome the measurement difference between the different baking ovens.Simultaneously, the preparation method of this standard sample is very simple.
Use is measured tobacco moisture through the baking oven of the diverse location of said method verification or the different baking ovens of same position, can obtain measured value more accurately about the standard sample content range, and same sample can obtain consistent result in different baking ovens.
The advantage of method provided by the invention is to solve different baking ovens and is detecting same sample water timesharing, the problem that there are differences, thereby effectively solve because the error that the difference of baking oven itself causes the goods water content detection to exist, and then can be by the arbitrary baking oven of verification as the instrument of demarcating the on-line moisture determination instrument, guarantee that different production lines, different processing stand produce the tobacco of same brand in quality of item stability and consistance.
Embodiment
Embodiment 1
The preparation of standard moisture sample: getting 1000 gram finished cut tobaccos, be ground into offal about 80 orders by comminutor, is 60 ± 2% with this batch sample in humidity, and balance is 96 hours in 22 ± 1 ℃ of climatic chambers of temperature.Get 30 gram samples with inquartation and divide three parts to measure by the standard method of existing determination of moisture in the process baking oven of thermometer calibration, its moisture is respectively 12.1%, 11.9%, 12.0%.Therefore, we this batch sample is defined as water percentage is 12.0% standard moisture sample.Sample with these standard moisture sample break into portions 50 grams, and be contained in by being 60 ± 2% in humidity, in the special-purpose pop can of balance after 24 hours, be 60 ± 2% in humidity in 22 ± 1 ℃ of climatic chambers of temperature, the warm and humid constant environmental baseline lower seal that temperature is 22 ± 1 ℃ stores.
Embodiment 2
From the sealing pop can, get standard model 30 grams among the embodiment 1 during each the use, evenly be divided into 3 parts, the baking oven of quality supervision measuring station is carried out repeatedly verification, up to this baking oven bioassay standard moisture sample value 12.0 ± 0.1% with till interior.
Check results is as follows:
Through verification more than three times, a repeatability is tested this baking oven and is confirmed as the determination of moisture confidence level greater than 95%.Can be used as and measure the baking oven of tobacco at goods moisture and the online Moisture Meter device of calibration.
Embodiment 3
Each with the standard model among the embodiment 1, with the method among the embodiment 2, the baking oven of A, B two processing stands is carried out repeatedly verification, up to this baking oven bioassay standard moisture sample value 12.0 ± 0.1% with till interior.In A, B two places the pipe tobacco that A ground produces is carried out water content detection.The result is as follows:
Because the pipe tobacco of A ground processing is through long-distance transporting, moisture has certain scattering and disappearing, and this is very normal, and also the description standard moisture sample has played due effect in the verification baking oven simultaneously.
